[Desktop-packages] [Bug 1504724] Re: lightdm crashed with SIGSEGV in munmap()
Sorry, but I don't see any evidence of pam's involvement here. The backtrace attached, with no resolved symbols, shows a stack contained entirely within ld.so plus some anonymous mappings. Based on some of the addresses there is *probably* stack corruption as well, but I definitely don't see anything pointing to pam. If you do, please let me know specifically what that is. ** Package changed: pam (Ubuntu) => lightdm (Ubuntu) -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to lightdm in Ubuntu. https://bugs.launchpad.net/bugs/1504724 Title: lightdm crashed with SIGSEGV in munmap() Status in lightdm package in Ubuntu: Triaged Bug description: crash at startup ProblemType: Crash DistroRelease: Ubuntu 15.10 Package: lightdm 1.16.3-0ubuntu1 ProcVersionSignature: Ubuntu 4.2.0-15.18-generic 4.2.3 Uname: Linux 4.2.0-15-generic x86_64 NonfreeKernelModules: nvidia ApportVersion: 2.19.1-0ubuntu2 Architecture: amd64 Date: Fri Oct 9 23:46:03 2015 ExecutablePath: /usr/sbin/lightdm LightdmGreeterLog: ** Message: Starting lightdm-gtk-greeter 2.0.1 (Aug 7 2015, 01:24:18) ** Message: [Configuration] Reading file: /etc/lightdm/lightdm-gtk-greeter.conf.d/01_ubuntu.conf ** Message: [Configuration] Reading file: /etc/lightdm/lightdm-gtk-greeter.conf.d/99_ubuntu-mate.conf ** Message: [Configuration] Reading file: /etc/lightdm/lightdm-gtk-greeter.conf upstart: indicator-application main process (2433) terminated with status 1 LightdmGreeterLogOld: ** Message: Starting lightdm-gtk-greeter 2.0.1 (Aug 7 2015, 01:24:18) ** Message: [Configuration] Reading file: /etc/lightdm/lightdm-gtk-greeter.conf.d/01_ubuntu.conf ** Message: [Configuration] Reading file: /etc/lightdm/lightdm-gtk-greeter.conf.d/99_ubuntu-mate.conf ** Message: [Configuration] Reading file: /etc/lightdm/lightdm-gtk-greeter.conf upstart: indicator-application main process (2426) killed by TERM signal ProcCmdline: lightdm --session-child 12 19 ProcEnviron: TERM=linux PATH=(custom, no user) SegvAnalysis: Segfault happened at: 0x7f8c59f0fb94 <_dl_fini+452>: add0x8(%rax),%r12 PC (0x7f8c59f0fb94) ok source "0x8(%rax)" (0x7f8c4a545e08) not located in a known VMA region (needed readable region)! destination "%r12" ok SegvReason: reading unknown VMA Signal: 11 SourcePackage: lightdm StacktraceTop: munmap () at ../sysdeps/unix/syscall-template.S:81 _dl_unmap_segments (l=0x1d2c910, l=0x1d2c910) at ./dl-unmap-segments.h:32 _dl_unmap (map=map@entry=0x1d2c910) at ../sysdeps/x86_64/tlsdesc.c:140 _dl_close_worker (map=map@entry=0x1d2c440) at dl-close.c:641 _dl_close_worker (map=0x1d2c440) at dl-close.c:125 Title: lightdm crashed with SIGSEGV in munmap() UpgradeStatus: No upgrade log present (probably fresh install) UserGroups: To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/lightdm/+bug/1504724/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : desktop-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp

[Desktop-packages] [Bug 1504724] Re: lightdm crashed with SIGSEGV in munmap()
This may be a teamviewer problem. I don't know if it is relevant, but when searching /var/log for any mention of munmap, I got the following results: dvs4@dvs4-E6540:/var/log$ sudo grep -R munmap * auth.log:Dec 7 08:31:22 dvs4-E6540 sudo: dvs4 : TTY=pts/2 ; PWD=/var/log ; USER=root ; COMMAND=/bin/grep munmap alternatives.log alternatives.log.1 alternatives.log.10.gz alternatives.log.11.gz alternatives.log.12.gz alternatives.log.2.gz alternatives.log.3.gz alternatives.log.4.gz alternatives.log.5.gz alternatives.log.6.gz alternatives.log.7.gz alternatives.log.8.gz alternatives.log.9.gz apache2 apport.log apport.log.1 apport.log.2.gz apport.log.3.gz apport.log.4.gz apport.log.5.gz apport.log.6.gz apport.log.7.gz apt auth.log auth.log.1 auth.log.2.gz auth.log.3.gz auth.log.4.gz boot.log bootstrap.log btmp btmp.1 chkrootkit ConsoleKit cups dirmngr dist-upgrade dmesg dmesg.0 dmesg.1.gz dmesg.2.gz dmesg.3.gz dmesg.4.gz dpkg.log dpkg.log.1 dpkg.log.10.gz dpkg.log.11.gz dpkg.log.12.gz dpkg.log.2.gz dpkg.log.3.gz dpkg.log.4.gz dpkg.log.5.gz dpkg.log.6.gz dpkg.log.7.gz dpkg.log.8.gz dpkg.log.9.gz faillog fontconfig.log fsck git-daemon gpu-manager.log hp installer kern.log kern.log.1 auth.log:Dec 7 08:32:45 dvs4-E6540 sudo: dvs4 : TTY=pts/2 ; PWD=/var/log ; USER=root ; COMMAND=/bin/grep -R munmap alternatives.log alternatives.log.1 alternatives.log.10.gz alternatives.log.11.gz alternatives.log.12.gz alternatives.log.2.gz alternatives.log.3.gz alternatives.log.4.gz alternatives.log.5.gz alternatives.log.6.gz alternatives.log.7.gz alternatives.log.8.gz alternatives.log.9.gz apache2 apport.log apport.log.1 apport.log.2.gz apport.log.3.gz apport.log.4.gz apport.log.5.gz apport.log.6.gz apport.log.7.gz apt auth.log auth.log.1 auth.log.2.gz auth.log.3.gz auth.log.4.gz boot.log bootstrap.log btmp btmp.1 chkrootkit ConsoleKit cups dirmngr dist-upgrade dmesg dmesg.0 dmesg.1.gz dmesg.2.gz dmesg.3.gz dmesg.4.gz dpkg.log dpkg.log.1 dpkg.log.10.gz dpkg.log.11.gz dpkg.log.12.gz dpkg.log.2.gz dpkg.log.3.gz dpkg.log.4.gz dpkg.log.5.gz dpkg.log.6.gz dpkg.log.7.gz dpkg.log.8.gz dpkg.log.9.gz faillog fontconfig.log fsck git-daemon gpu-manager.log hp installer kern.log kern.log .1 grep: teamviewer/lightdm: No such file or directory ls -al in /var/log shows the following link for teamviewer lrwxrwxrwx 1 rootroot 24 Jan 15 2015 teamviewer -> /opt/teamviewer/logfiles Checking that link includes the following lightdm link: dvs4@dvs4-E6540:/var/log$ ls -al /opt/teamviewer/logfiles/ lrwxrwxrwx 1 root root 41 Dec 10 2014 dvs4 -> /home/dvs4/.config/teamviewer10/logfiles/ lrwxrwxrwx 1 root root 47 Feb 3 2015 lightdm -> /var/lib/lightdm/.config/teamviewer10/logfiles/ Checking where that should point to shows it is not there: dvs4@dvs4-E6540:/var/log$ sudo ls -al /var/lib/lightdm/* ls: cannot access /var/lib/lightdm/*: No such file or directory Because of the similarities and because I am the only user on this machine, I changed the lightdm link to match the dvs4 user link: lrwxrwxrwx 1 root root 41 Dec 7 08:36 lightdm -> /home/dvs4/.config/teamviewer10/logfiles/ I have never seen this particular error before, but I have had some annoying glitches with the way Teamviewer starts, so I will try it this way for a while and see if it seems to make any difference... -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to lightdm in Ubuntu. https://bugs.launchpad.net/bugs/1504724 Title: lightdm crashed with SIGSEGV in munmap() Status in lightdm package in Ubuntu: Confirmed Bug description: crash at startup ProblemType: Crash DistroRelease: Ubuntu 15.10 Package: lightdm 1.16.3-0ubuntu1 ProcVersionSignature: Ubuntu 4.2.0-15.18-generic 4.2.3 Uname: Linux 4.2.0-15-generic x86_64 NonfreeKernelModules: nvidia ApportVersion: 2.19.1-0ubuntu2 Architecture: amd64 Date: Fri Oct 9 23:46:03 2015 ExecutablePath: /usr/sbin/lightdm LightdmGreeterLog: ** Message: Starting lightdm-gtk-greeter 2.0.1 (Aug 7 2015, 01:24:18) ** Message: [Configuration] Reading file: /etc/lightdm/lightdm-gtk-greeter.conf.d/01_ubuntu.conf ** Message: [Configuration] Reading file: /etc/lightdm/lightdm-gtk-greeter.conf.d/99_ubuntu-mate.conf ** Message: [Configuration] Reading file: /etc/lightdm/lightdm-gtk-greeter.conf upstart: indicator-application main process (2433) terminated with status 1 LightdmGreeterLogOld: ** Message: Starting lightdm-gtk-greeter 2.0.1 (Aug 7 2015, 01:24:18) ** Message: [Configuration] Reading file: /etc/lightdm/lightdm-gtk-greeter.conf.d/01_ubuntu.conf ** Message: [Configuration] Reading file: /etc/lightdm/lightdm-gtk-greeter.conf.d/99_ubuntu-mate.conf ** Message: [Configuration] Reading file: /etc/lightdm/lightdm-gtk-greeter.conf upstart: indicator-application main process (2426)
